It is as easy to manipulate people as a politician as it is to change the content of a social media post after garnering thousands of likes.
With the above gimmick, the flat earth society can be changed into the trapezoidal earth society in a month or two’s time.
As you get manipulated, the people you influence also get manipulated as part of the chain reaction. Finally, the mass narrative and support for the topic get changed. Saying that, the more bias one has toward something, the easier it gets to manipulate them.
Thinking for yourself while setting your biases aside is hard to do but an important enough task to undertake for breaking the chain reaction.
